Cell Structure: Vacuole in Cells.

Question 1

What is a key features of animal cell vacuoles?

Answer 1

= temporary
= small structures
= not central

Question 2

What are the key features of an plant cell vacuole?

Answer 2

= central
= large
= permanent

Question 3

What is the membrane that surrounds the vacuole?

Answer 3

= tonoplast.

Question 4

What is the role of the tonoplast?

Answer 4

= Controls which chemicals enter and leave the vacuole.

Question 5

What is cell sap?

Answer 5

= contains dissolved sugars
= mineral salts
= amino acids
= can contain other molecules
= can contain waste products

Question 6

What is another feature of cell sap?

Answer 6

= Low water potential
= water moves into plant by osmosis and enters vacuole
= causes hydrostatic pressure acting outwards causes cytoplasm to press against cell wall
